Would this be able to be made with a 0.300″-0.301″ bore ride section? This would make a good 308 win design.

I’ll go along with Tomme on the 180 gr K-31. If the nose was widened from .297″ as it is now, to about .301″, it would be perfect for the .308 Winchester. The length at 1.085″ would be just right to fit in a standard M1A/AR-10/FAL type .308 magazine, and still keep the gas check within the neck of the case. It looks like an almost ideal design for the .308 Winchester, other than the nose diameter being too small.

For anyone not familiar with the K-31 design, see http://noebulletmolds.com/NV/product_info.php?cPath=30&products_id=44&osCsid=pfvtju1s5i3v53f36j8fn3fbp4

To get the nose out to .301 the body would have to be .315
Could be sized but it may be a bit much for some

A new tool would take 15 orders but it could be done

If the whole cavity was orbited out .004″ larger, what effect would that have on the gas check shank area of the bullet? I think I’d be more concerned about that than I would about sizing the bullet down from .315″ to .311″.

I would rather have a purpose made design with the cherry cut to make the bullet the proper size in the first place. I’ll sign up for one of those right now. Put me down for a 4 cavity.

Thanks,

Dave

We have some Voodoo magic that takes care
of the GC shank – not a problem there 
But a new tool would be the way to go.

If there is enough interest

I would be in for a four cavity if the driving bands would be .311″ and nose .301-.302″

I REALLY WANT one!!!
